Innotech Growlight’s Proton Pro 300W is a COB LED grow panel designed for 1 m² tents. It uses six 50 W Bridgelux COBs (300 W total, ±5%) behind bubble lenses to improve uniform light spread. The spectrum spans 380–780 nm and includes UV, with a wide 120° beam. Power is switchable between 150 W and 300 W. At 30 cm, PPFD is about 1145 μmol/m²/s over roughly 1×1 m. The fixture measures 445 × 254 × 50 mm, weighs 4.2 kg, and runs on AC 85–265 V, 50–60 Hz with active cooling (aluminum heat sink + fans) and PF 0.95. Recommended coverage is 100 × 100 cm in bloom and up to 120 × 120 cm in veg.
